Everyone at the office was SO SWEET! I came in for allergy testing, which is nothing but an uncomfortable experience, and every one of the providers I met with treated me with nothing but patience and care. From the moment I was making my appointment, everyone was respectful and so very caring. Allergy testing is a nerve-wracking experience but I felt supported throughout the whole appointment.

Dr Barmettler listened and was engaged. She typed into the computer as I told her things. [redacted] She talked with me very well about the upcoming tests and procedures I needed providing me with a copy of them. Very useful. She is pleasant and personable. Had some gaps in knowledge about Simponi and risk factors. [redacted]

Nurse forgot about the expiration of the timer on my allergy test and didn't show up for about 5 minutes after the timer went off. Raised a question about attentiveness, especially to details.

I have complete confidence in Dr Barmettler and am extremely satisfied. She was responsive and helpful, and developed a clear strategy to deal with my issues. While initially I could not arrange an in-person appointment for seven months, within days her office called to set up a virtual and I was able to have my problems attended to.
